Clinical development of estrogen modulators for breast cancer chemoprevention in premenopausal vs. postmenopausal women. [Record Supplied By Publisher] J Cell Biochem 2000;77(S34):103-114 (ISSN: 0730-2312) Lawrence JA; Malpas PB; Sigman CC; Kelloff GJ [Find other articles with these Authors] Chemoprevention Branch, Division of Cancer Prevention, National Cancer Institute, Bethesda, Maryland. Tamoxifen has proven to be beneficial in the chemoprevention of breast cancer in women at increased risk for the disease. Other compounds that mediate the estrogen pathway remain to be tested for clinical efficacy. The mechanism of action, efficacy, and dose response of the estrogen modulators is determined by the hormonal milieu of the host which should be considered in the early clinical trials for dose range finding studies and surrogate endpoint biomarker (SEB) evaluation. This review presents the hormonal effects to consider in the clinical testing of an agent in premenopausal vs. postmenopausal cohorts. Recommended SEBs that may be evaluated in Phase I/II clinical trials of estrogen modulators for breast cancer chemoprevention are presented. J. Cell. Biochem. Suppl. 34:103-114, 2000.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
